Dynapac CP221 Parts Catalog: Factory Spec Parts Identification

I’ve been an ASE Master Technician for 28 years. When a CP221 comes into my shop with a leaking wheel motor or a cracked suspension arm, I don’t have time to guess which part number fits. That’s why I keep a copy of the Dynapac CP221 Parts Catalog within arm’s reach. This isn’t some aftermarket reprint that tries to compress 331 pages of factory drawings into a handful of sketches. It’s the real thing – the same document the Swedes at Dynapac use to ship replacement parts from Karlskrona. If you’re rebuilding a pneumatic tire roller and you don’t have this, you’re ordering blind.

What the Dynapac CP221 Parts Catalog Actually Contains

Open this PDF and you’ll find exploded-view drawings for every major assembly on the roller. Brake system, steering, ballast tanks, wheel motors – each group gets its own section with callouts matching the parts list. The manual covers serial number ranges from 22620221 through 22620277, which covers the Cummins 4BT 3.9C and 4BT 3.9C Elite diesel engines. Every part has a unique numerical identifier. You don’t cross-reference blurry photocopies.

331 Pages of Exploded Views and Part Numbers

That number is not a typo. Three hundred thirty-one pages dedicated to one model – the CP221 pneumatic tire roller. Each page is a clean factory scan, not a scanned copy of a copy. The drawing quality matters when you’re trying to tell a M10 bolt from a M12 in a tight frame area. You need to see thread pitch and head markings. This catalog gives you that.

The section on the Cummins 4BT 3.9C alone breaks down the injection pump, turbo, and front gear train with separate exploded views. If you’re rebuilding a roller that’s sat for two years, you’ll be digging into those pages.

Why Factory Serial Number Coverage Matters

Dynapac issued six revisions of this catalog between 1998 and 2004. Each revision added or deleted parts based on production changes. The SCP221-1EN4 edition you’re looking at is the final update – it covers the last production run. If your roller’s serial number falls outside the range listed on page 3, you need an earlier issue. That’s not a problem aftermarket parts sites will tell you. They’ll sell you a generic parts list and leave you holding a wrong bearing. For an overview of how compaction equipment fits into the broader Automotive Industry Overview, that’s fine. But for parts identification, stick to the OEM source.

Order Spare Parts Correctly

Page 4 of the manual spells out exactly what Dynapac requires when you place an order: machine type, roller serial number, quantity, part number, part denomination, and dimensions if ordering by length. That six-point list eliminates every excuse for a wrong shipment. I’ve seen shops skip the serial number and end up with a brake caliper that doesn’t fit. Don’t be that shop.

The Automotive Industry Overview also provides context on safety standards, but your immediate job is to get the right hardware. This catalog is your cheat sheet.

Diesel Engine Section: Cummins 4BT 3.9C

The engine group in this parts catalog includes all serviceable components – from the oil pan gasket to the fan hub. Each part has a reference number that ties directly to the Dynapac ordering system. If you need a replacement injector for a 4BT 3.9C Elite, you can verify the exact part number before calling your dealer. No more “it looks like this one” guessing.

Period.

Frequently Asked Questions

Does this cover the Cummins 4BT 3.9C Elite?

Yes, it does.

How do I make sure I order the right part?

Cross-reference your roller’s serial number against the range given on page 3 (22620221 – 22620277) and use the six ordering details from page 4. Every part in this catalog has a unique number. If you provide the serial number, part number, quantity, and denomination, the dealer can confirm fitment. Never order without checking the serial number against the catalog’s valid range; one digit off can mean a different casting. For example, the water pump for a 22620221 roller may differ from one built after 22620250. The exploded views show these variations with separate callouts. Always open the manual, find your engine variant, and match the part number exactly. That stops 90% of wrong-part returns.

This catalog sits on my bench next to my torque wrenches. It’s the only parts reference I trust for a CP221. Access the Factory Manual and stop guessing which part goes where.
